(3)look for 意为”寻找”,是常用语.例如:
He is looking for his pen everywhere .
他在到处找他的钢笔.Using his hybrid rice , farmers are producing harvests twice as large as before.
用他的杂交水稻种子,农民们种出比以前多一倍的粮食.在表示三倍或三倍以上的倍数时,我们通常常用time 一词. 用time 表示倍数有以下几种句型:主语+谓语+…times + as + 形容词 + (n.) + as + 被比较的内容. 例如:

This year we have produced twice as much grain as we did last year . 我们今年生产的粮食是去年的两倍.
The box is one -- third bigger than that one. 这个盒子比哪个盒子大三分之一.
The output value was 59 percent higher than that in 1976. 产量比1976年增长百分之五十九.
